An inode is a data structure used to keep information about a file on your hosting account. The number of inodes indicates the number of files and folders you have. This includes everything on your account, emails, files, folders, anything you store on the server.
The 50000 inode limit is now increased to 100000.
What is the 100,000 inodes limit?
It means, shared servers only allow 100,000 files per cPanel. You may slightly exceed this limit, but then we will not continue to create automatic backups.
It will be a TOS violation if you continuously publish and delete large numbers of files, like 10,000 at a time.
It will be a TOS violation if you are in excess of 250,000 files.
